Improvement in plows



UNITED STATES PATRICK HENRY STARKE, OF RICHMOND, VIRGINIA.

IMPRovl-:MENT IN PLows.

Specification forming part of Letters Patent No. 117,574, dated August1, 1871.

To all whom t may concern:

Be it known that I, PATRICK HENRY STARKE, of Richmond, in the county ofHenrico and State of Virginia, have invented a new and usefulImprovement in Plow; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same, reference being had to theaccompanying drawing forming part of this specication, in which- Figure1 is a perspective view of my improved plow. Fig. 2 is a detailsectional view of the same. Fig. 3 is a detail view of another formofmold-board.

Similar letters of reference indicate corresponding parts.

My invention consists in an improved con struction of standard forturn-plows, as hereinafter fully described and subsequently pointed outin the claim.

B is the point, C the mold-board, D the landside, E the beam, and I Ithe handles of a turnplow. A represents my standard, which is inclinedrearward and curved on the front edge to prevent it from gathering grassand roots and becoming choked. The upper part has a forward projectionor bearing, a', and a rear one, F, for

the beam. The rear bearing or projection F is slotted in the arc of acircle, whose center is in. the front bearing a. The latter overlaps thebeam on its top surface.` The beam E is thus provided with ajournal-stud, G, which turns in bearings a', while the bolt H traversesthe arcslot of thev bearing or projection F. The beam may be fastened atany point in this slot by any suitable fastening device, but I preferthe double ratchet shown in Fig. 2 of drawing.

By turning the beam E on its center of motion at G the plow may be madeto run deep or shallow.

Having thus described all that is necessary to` a full understanding` ofmy invention, what I esteem to be new, and desire to protect by LettersPatent, is-

'Ihe plow-standard A, having projection a overlapping` the top of thebeam, and the arcslotted projection F, combined with a beam, E, having'the studs G H, to enable the said beam to be turned on a center at G,and thereby regulate the depth ofthe plow.

PATRICK HENRY STARKE.
